WATER-CLOSET VALVE AND OPERATING MECHANISM THEREFOR.

SPECIFICATION forming part of Letters Patent No. 435,021, dated August 26, 1890. Application filed May 31, 1889. Serial No. 312,716. (No model.)

To all whom it may concern.-

Be it known that I, TIMOTHY MOHUGH, of Vakefield, in the county of Middlesex and State of Massachusetts, have invented certain newand usefulImproveInentsin ater-Closet Valves and Operating Mechanism Therefor, of which the following is a specification.

This invention relates to valves for controlling the discharge of water from supply- IO tanks of water-closets in which the closing movement of the valve is retarded by a cushion or body of water which supports the valve when it is raised and is allowed to escape slowly, and thereby permit a slow descent or closing movement of the valve.

The invention consists, first, in certain improvements in valves of this class, whereby simplicity of construction and efficiency of operation are secured, and in certain improvements in means for operating a water closet valve and giving a preliminary and a second or after wash, all of which I will now proceed to describe and claim.

In the accompanying drawings, forming a part of this specification, Figure 1 represents a sectional view of a water-closet su pply-tank having my improved valve and valve-operating mechanism. Figs. 2 and 3 represent vertical sections of the valve, the former showing it closed and the latter showing it raised. Fig. 4 represents a section on line 00 a, Fig. 3.

In the drawings, a represents the supplytank having attached to its bottom the outlet pipe or fitting h, the upper end of which 5 is the valve-seat c.

d represents the valve, which is formed to bear on the seat 0, and has a vertical cylindrical chamber e, the upper end of which is closed by a head or cap f; while its lower end has a cross-bar or guide g, through which passes a fixed tubular stem h, supporting a fixed piston 1' within the cylinder. Said stem is affixed to a cross-barj on a ring or spider m, which is screwed in the outlet-fitting,

said cross-bar having a channel is extending through it and receiving water from the lower portion of the supply-tank when the valve is raised,,the water entering the channel it and passing from thence upwardly through the 5b tubular stem 76 and through the piston 2' into the cylinder 6 above the piston, as indicated by arrows in Fig. 3. The piston has a downwardly-closing valve 0, which rises to admit water to the upper portion of the cylinder when the valve is being raised, but closes to prevent the escape of water through said stem when the valve is falling. In the head i of the cylinder is an outlet-passagep, formed in a tube or nipple q, the latter having a screw 0", which can be adjusted to regulate the size of the outlet-passage. Then the valve is I released after being raised, the body of water drawn by the upward movement of the valve into the cylinder above the piston supports the weight of the valve and permits the same to descend only as fast as said water escapes through the outlet 1). The valve is connected bya link .9 with a rod t, which is ,fitted to slide in a fixed guide t, attached to a crossbar a on the top of the tank a. Said rod has a head to at its upper end, which is engaged by a toe-piece or latch r, pivoted at o to a lever 20. Said lever is pivoted at y to a fixed ear w, and is connected at its outer end by a rod 2 or other suitable connecting device with 5 a water-closet seat or other means for pulling down said rod .2 and the end of the lever to which the same is attached. When the rod 2 is pulled down, the end of the lever w, carrying the toe o, is raised, and said toe is caused by its engagement with the headit to lift the rod 75 and the valve d, connected therewith, the toe being held rigidly against the downward pressure of the head a upon it by a fixed lug 2 on the lever 20, bearing on the rear end of said toe, as shown in Fig. 1. hen the toe o rises beyond a given point, it passes out of engagement with the head to, the latter being thus released and allowing the valve to fall.

A represents a lever, which is pivoted'at B to an ear 0 and has a shorter arm, to which is pivoted a toe D, and a longer arm, to which is attached a weight E. The lever 10 is extended at the end opposite the one to which 5 the rod z is connected, and said extended end is provided with a roller G, which bears against the under side of the longer arm of the lever A. It will be seen, therefore, that the move ment of the leverw, caused by the downward 10o movement of rod 2, will raise the roller G and cause it to raise the longer arm and depress the shorter arm of the lever A. The toe D is thus brought into engagement with the head u of the valve-lifting rod 75 after the latter has been released or disengaged from the toe 1;. Now, upon the release of the rod 2 the Weighted arm of lever A will fall, thus restoring lever w to the position shown in Fig. 1 and at the same time raising the toe D (which is now engaged with head a) and cansing said toe to raise the rod tand valve d until the toe passes out of engagement with the head a, after which the lever A comes to restand all the parts are as shown in Fig. 1. It will be seen that the depression of rod 2 causes a preliminary raising of the valve by the lever w, while the release of said rod causes a second raising of the valve by the action of the Weighted lever A, which is set for action by the valve-raising movement of the lever 10.

The construction of the described valve operating devices is simple, and therefore not liable to get out of order.

I claim- 1. In a water-closet valve, the combination,

with the outlet pipe or fitting, of the cylindrical valve designed to be seated on said outlet-pipe and having a lower cross-bar g and a central chamber closed at its upper end and provided with an opening, the adjustable screw working in said opening, the vertical hollow stem h, having a lower crossbar provided with a central channel and rigidly secured on the upper end of said outlet-pipe and extended through an aperture of said cross-bar g, and the piston formed with the upper end of said stem and having a valve 0 secured thereto, substantially as set forth.

2. The combination, with a tank and avalve therein, of a headed operating-rod connected with said valve, an operating-lever 10, having a pivoted toe to engage the head of said rod, and a weighted lever A, also provided with a toe to engage said head of the operating-rod, said lever w having its end extended beneath said lever A beyond the fulcrum of the latter, so as to raise the same when operated, substantially as set forth.

3. The combination, with a tank and a valve therein, of a headed operating-rod connected with said Valve, an operating-lever 10, having a pivoted toe and a fixed stop therefor and having a roller secured to its extended end, and the weighted lever A, also having a toe to engage the head of said rod, substantially as set forth, said roller being beneath said lever A, with which it is designed to come in contact to effect the raising thereof when lever w is operated, as stated.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 17th day of May, A. D. 1889.
